SiFly Stellar S eFoil Set
The SiFly Stellar S eFoil Set is a high-performance eFoil designed for intermediate and advanced riders seeking a sporty, precise, and engaging ride. The compact 98-liter board, featuring a full carbon sandwich construction and a lightweight EPS core, is designed to offer greater stiffness, reduced swing weight, and an immediate response during carving and maneuvers.
Measuring 161 x 66 cm, the Stellar S prioritizes agility and control in flight. It is the ideal choice for those who want to push their turning performance, improve their carving ability, and achieve a more direct and responsive feel underfoot, both on flat water and in small-wave conditions.
The SiFly carving machine
The Stellar S takes eFoiling toward a more dynamic and aggressive ride. The compact volume, reduced weight, and carbon construction allow the board to react quickly to changes in rider pressure, facilitating tighter turns, smoother transitions, and a sportier ride.
The hull geometry is designed to reduce the impact of touchdowns: the optimized rocker helps the board release the water progressively, limiting nose-diving and promoting a more controlled relaunch.
Main features
Carving performance
The compact shape of the board and the reduced swing weight allow for quick changes of direction, more incisive turns, and precise handling even during the most technical maneuvers.
Full carbon construction
The carbon sandwich construction with a lightweight EPS core increases the board's stiffness, reduces weight, and contributes to a more direct response during riding.
Compact 98-liter volume
The 98 liters offer an agile and sporty behavior, suitable for riders who have already gained good confidence with eFoil takeoffs, balance, and control.
Anti-dive architecture
The board's rocker promotes smoother and more controlled touchdowns, helping to reduce the tendency of the nose to dive when the board returns to contact with the water.
Integrated mast base
The integrated mast foot improves touchdown management and contributes to a more stable feel during contact and relaunch phases.
Up to 120 minutes of battery life
The PowerCell LR battery offers up to 120 minutes of estimated battery life, which varies based on the rider's weight, the wing used, speed, water conditions, and riding style.

Who is it recommended for
The SiFly Stellar S is aimed at intermediate and advanced riders who have already developed good confidence in eFoiling and want a more compact, stiff, and responsive board. Its sporty character makes it particularly interesting for those who want to improve their carving, layback turns, and riding in more dynamic conditions.
The 98-liter volume requires greater confidence compared to larger boards. For heavier riders or those who want a simpler and more stable approach, it is advisable to consider a high-lift wing configuration.
Maintenance and use
After every use in salt water, rinse the board, mast, wings, motor, and external components with fresh water. Before storing the equipment, check that connections, the battery compartment, and electronic components are clean and dry.
Actual battery life may vary from the maximum estimated value based on the rider's weight, wing configuration, riding speed, accelerations, temperature, wind, and water conditions.
